Embodiment Construction

[0033]The present disclosure relates to elasticized materials comprising bond patterns having beneficial properties. In some embodiments according to the present disclosure, the bond pattern used to form the elasticized material allows for any positioning of the elastomeric strands during the forming process while ensuring bonding of the strands within the material. In other embodiments, the bond pattern used may cause uneven ripples of the elasticized material when the material is in a relaxed state. The non-uniform corrugations may have one or more benefits, including being an obstacle to fluid flow and also providing a relatively flat material, compared to alternative bond patterns that form distinct continuous ridges and valleys when the material is in a relaxed state.

[0034] Each example is given by way of illustration and not meant to be limiting. For example, features illustrated or described as part of one embodiment or figure can be used on another embodiment or fi...

Abstract

The present invention discloses elasticated materials and methods of forming elasticated materials. In one embodiment, an elasticated material may comprise a first layer of material, a second layer ofmaterial bonded to the first layer of material by a plurality of bonds arranged in bond groupings aligned in bond grouping rows, and an elastomeric strand extending in the lateral direction and disposed between the first layer and the second layer, the elastomeric strand extending between a first bond and a second bond of a first bond grouping with the first bond and the second bond of the firstbond grouping being spaced apart in the longitudinal direction a distance less than an un-tensioned diameter of the elastomeric strand. A portion of a second bond grouping may laterally overlap the first bond grouping with the second bond grouping disposed row that is longitudinally adjacent to the row containing the first bond grouping.

Description

[0001] Cross references to related patent applications [0002] This application claims the benefit of co-pending U.S. Provisional Application No. 62 / 491503, filed April 28, 2017, entitled "ELASTICATED MATERIAL WITH NON-CONTINUOUS CHANNELS." technical field [0003] The present disclosure relates to elasticized materials, and more particularly to elasticized materials having discontinuous channels. Background technique [0004] Elasticized materials are used in many different applications, including in various garments and absorbent articles. This elasticized material can be used as part of a waistband, leg cuffs, barrier cuffs, or other components of garments and absorbent articles to provide a beneficial fit, to help prevent the seepage of body exudates, or to impart other benefits . [0005] Many existing garments and absorbent articles include elasticized materials comprising elastic strands positioned between and secured to material layers with adhesives. Some prior ...
